The CR510 dataloggers are a smaller version of our popular CR10X dataloggers. They provide a lower-cost datalogger alternative for measurements of a limited number of sensors, yet can be used with most of our telecommunication devices such as cellular telephones, RF UHF/VHF RF modems, and satellite transceivers. The CR510-series dataloggers use external power supplies and keyboard displays. They are not compatible with multiplexers, SDM devices, or thermocouples.

The CR10 was a modular datalogger consisting of a Measurement and Control Module, CR10WP Wiring Panel, and internal software (PROM).

THIS PRODUCT HAS BEEN RETIRED. IT WAS REPLACED BY THE CR3000 MICROLOGGER.

The CR23X is a self-contained, rugged datalogger that can measure most sensor types directly, communicate via modems, reduce data, control external devices, and store both data and programs in either non-volatile Flash memory or battery-backed SRAM.

The CR23X has an integral, 2-line, alphanumeric display and power supply. A battery-backed, real-time clock and either 2M or 4M of nonvolatile data storage is included (depending upon model purchased). The CR23Xs are available with a sealed rechargeable battery base, an alkaline base, or in a low-profile version without batteries.

Availability of the CR23X may be limited; please contact an applications engineer to discuss your measurement needs.

The CR10X has been replaced by the CR1000. The CR10XWP Wiring Panel and the CR10XTCR Thermocouple Reference Thermistor (for use with the CR10XWP) are still available.

The CR10X-series is a compact, modular line of dataloggers with a measurement and control module, external power supply, and keyboard display.

The CR21 featured an integrated design with built-in power supply, keyboard, and display. It looks very similar to, and is often confused with its replacement, the 21X Micrologger. The CR21 stored up to 608 data points in internal memory.

A typical field-based CR21 consisted of:
    CR21 or CR21L Micrologger with
    CR21 Instruction Set (PROMs)
    Alkaline or Rechargeable Power Supply (in base)
    Weatherproof Enclosure (new and old)

The CR9000C was a modular, multiprocessor system that provided precision measurement capabilities in a rugged battery-operated package. It was our "compact" version of the CR9000; larger versions were available as the CR9000 and CR9000DC.

The CR9000 was a modular, multiprocessor system that provided precision measurement capabilities in a rugged battery-operated package. The CR9000 consisted of a base system and a chassis with I/O module slots that accepted up to nine user-selected modules. A compact version of the CR9000 was available as the CR9000C, which accepted up to five user-selected modules. The CR9000s' powerful instruction set supported measurement of most sensor types, on-board processing, data reduction, and intelligent control.

The BDR301 was a compact, self-contained datalogger. It included a sealed enclosure, 32-character alphanumeric display, and an RS-232 interface for connection to laptop computer (its only data retrieval method).

Software support for the BDR301 was provided by PC300 on 3.5" diskettes (typically running on a battery-powered laptop computer). The BDR301's require special connectors and their data file format is not compatible with the CR500, CR510, CR10(X), or 21X files.
